Do you have VERY bad periods, too?

I have bad periods. I have been on a golf getaway for the past week and for the first time I broke 90 then I did it again the next day. got one rain day then went back and to the driving range and tried to fix my driving as it is normaly the worst part of my game and got my swing down better the first couple holes where great but then it all went down hill. I could not hit a clean approach to save my soul. The more I got mad at that the more I started thinking about it. the more I thought about it the worse it got. then I seemed to forget everything about my driving so that too went south. by the 18 hole I just wanted to get out. the game is as much mental as physical in both playing and skill. I would say take some time at a range and work on a pre shot routine. take some time for your practice, you line up. and then one good deep breath. How ever you could be like me and that would still be too much thinking. I have to line up and swing. everyone is different. You just have to figure out what works to clear your mind. and like stated if nothing you try seems to work, get some time with a trainer to help. it's not bad to ask for help. But as for do I have off periods. I am only human and not pro. I don't know the perfect key to consistancey nor have do I have a personal trainer to work with. We don't make the big bucks out there so just remeber you just want to have fun.
